Open the Hero Summon in the lobby and spend Gems or Gold to pull units. Hero Summon banners rotate every hour, while Special Summon and Dual Starhunt banners cost Stardust and feature limited units. Hitting the 5-star pity — saving around 3,600 Gems — guarantees a legendary result.

Meta S-tier units include Blackstache (Final), Golden Supreme-Leader Mikato, The Path, Flaming TigerGen, Koku Black Pink, Zorr, Kura, Onwin and Jokato Koju. Strong A-tier all-rounders include Whitestache (Final), All Powerful, Genie, Hammer Giant and Ruffy (4th Form). Check our tier list for the full rankings.

Traits are random modifiers rolled onto units at the Robot in the lobby, or from your inventory using Trait Burners. The All Star trait is the best S-tier roll and grants a massive damage boost. Reroll unwanted traits with Trait Burners until you hit the buff you want.

Reach level 100 to unlock World II. Once you hit level 100, enter the portal located south of World I's spawn. World II brings a new set of harder maps, stronger enemies and fresh challenges with better rewards.

Shiny units are special variants with a cosmetic golden glow that can appear when summoning or evolving any unit. The exact rate is not officially confirmed, but the community estimates around 10%. Shinies are purely cosmetic and do not change a unit's stats or abilities.

Players can trade units with each other in the trading hub. Values are player-driven with no official price list. Limited, event and holiday units are often only obtainable through trading. Trading for Robux or real money is strictly prohibited.

Stardust is the premium currency used for Special Summon and Dual Starhunt banners, which feature limited units and stay active longer than Hero Summon. You can earn Stardust from codes, events and gameplay. In Special Summons, every four paid 10-summons makes the fourth one free.

PvP and Battle mode are currently under maintenance and not playable as of August 2026. When available, PvP lets you battle other players' teams. Check the update board and our updates page for news on when PvP returns.
